MULTIAXIAL RATCHETING-FATIGUE INTERACTION OF SS304 STAINLESS STEEL

摘要：

The ratcheting behavior and fatigue failure of SS304 stainless steel were investigated by multiaxial cyclic stressing tests with two kinds of loading paths. The multiaxial ratcheting deformation and low cycle fatigue (LCF) properties, as well as their interaction were discussed. It is shown that progressive multiaxial ratcheting deformation can induce the decrease of fatigue life for SS304 stainless steel, and the ratcheting behavior and fatigue life of the material are depended on mean stress, stress amplitude and the shape of loading path.
